Extract from back cover of book:
Harvesting wood entails cutting trees to supply material for solid or composite wood products (furniture, etc.), paper, and many others including fuelwood. Cutting trees does not necessarily mean destroying a forest, as some believe, provided that the forest is properly managed on a "sustained yield" basis, which dictates that only a volume equivalent to the yearly growth is removed, and regeneration is secured by natural or artificial seeding or planting. Part A of this book presents, in a comprehensive but concise manner and a universal approach, generalized technical, labor, and economic considerations of harvesting wood, within the context of practicing proper forestry and protecting the natural environment of the forest.
Pine resin is a secondary but important forest product in many countries a material adaptable to a variety of uses, such as making paper, adhesives, paints, pharmaceuticals, aromas, ink, and other products. Part B deals with harvesting resin with regard to techniques, consequences to trees, and factors affecting production.
An Appendix includes examples of procedures of harvesting wood and pine resin in a number of countries, cost calculations, time studies, and a harvesting contract.
Harvesting Forest Products contains world-wide information on harvesting in forests, a great number of illustrations, and extensive, international bibliography, separate for wood and resin; it is a useful reference or teaching aid for forestry students and foresters, forest technicians, forest labor (training), forest owners, and forest-products industries.
